18 Claims.

This invention relates to a hasp lock of the type employing a hasp-carried latching bolt which may be locked by a key. Such a hasp lock is usually employed on suitcases, trunks, traveling bags, or the like, but, of course, may be employed for securing together'any two contiguously disposed parts.

The object of the invention is to provide a hasp lock of this character which is extremely simple in construction in that it is constituted of very few parts and wherein the elements of the lock are closely and compactly organized, and this in such a way as to provide for smooth and effective action. The lock is constituted, except for springs, entirely of sheet metal stampings, and these are held assembled by appropriate holding or guide lugs so that no riveting or welding is necessary to maintain the major elements assembled in proper cooperative relation,

Another feature of the lock resides in the special manner in which the hasp and keeper are constituted and cooperatively interrelated, the structure bein such that the two lugs which guide the latching bolt, and retain it assembled with the hasp body plate, positively thoughre-.

leasably interlock with a locking shoulder on the keeper plate (in the locked position of the parts) to take the stress of holding the contiguously disposed parts with which the hasp and keeper'are associated against movement away from each other, the latching bolt serving only to exert its latching or looking function.

Another feature of the lock resides in the special way in which the latch spring is combined with the latching bolt and with its tumbler, the organization being such that the spring serves not only to exert the required biasing action on the latching bolt, but also functions to releasably hold the tumbler in the position to which it is adjusted by the key.

Another object of the invention is to provide a hasp lock wherein the means employed to-pivotally or hingedly connect the'hasp to one of the contiguously disposed parts to which the hasp is applied is so constituted as to completely enclose the hinge pin and hinge barrels of the pivotal connection, thereby preventing unauthorized removal of the hinge pin and unauthorized removal of the hasp, as well as improving the appearance of the structure.

Other objects and advantages reside in certain novel features of the construction, arrangement,

and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference be-.

Figure 18 is a central vertical cross section showing a keeper construction illustrated in Figures 1 and 2 adapted for a recessed type of attachment to its receptacle part.

Referring to the drawings, and more particularly to Figures 1 to 3, P and P designate two contiguously related parts, for example, the sections of a suitcase or the body and lid of any other similar receptacle. The hasp which is applied to the part P is designated generally at H and is pivotally or hingedly interconnected with the part P by connecting means designated as a whole at C. The hasp H cooperates with a keeper designated generally at K, which is applied and secured to the part P.

The hasp H comprises a body plate I constituted of a sheet metal stamping which is shaped and fashioned as shown in detail at Figures 10 and 11. The body plate I is provided with a marginal flange 2 to adapt it to encase and guide the latching bolt and the lock therefor in a manner to be hereinafter more fully described. The enlarged end of the body plate I is provided with a curled or rolled, extension providing a hinge barrel 3 centrally and symmetrically disposed With respect to the enlarged end of the body plate. The hinge barrel 3 is fitted between correspondingly formed, although shorter hinge, barrels 4 and 5 integrally formed with an attaching plate 6. The attaching plate 6 is disposed against the outer surface of the part P and it has attaching prongs 'I integral with its rear edge on the opposite sides of a tailpiece or extension 6' also integralwith the, attaching plate and giving it a broader bearing on the part P. The attaching prongs I are driven through the part P and staked over as at I (see Figures 2 and 3) to securely and rigidly fasten the attaching plate 6 to the part P. As shown in the drawings, the prongs I have their inner ends split and the portions of the inner ends of each prong are staked or clinched over in opposite directions. While this is desirable, it is not essential since an unsplit prong with its inner end staked over in one direction may be employed. A hinge pin 8 is fitted in the alined hinge barrels 3, 4, and 5 to pivotally interconnect the body plate I of the hasp to the attaching plate 6. A casing 9 is provided for hinge barrels {I and 5, the hinge pin 8, andq. the attaching plate 6. This casing is a sheet metal stamping shaped and fashioned as shown in detail in Figures 16 and 17, and provides a complete enclosure for the hinge barrels 4 and 5, the

hinge pin 8, and the attaching plate 6. In carry-y ing'out this purpose, the body portion 9 of the casing 9 is flanged to provide a box-like enclosure for the attaching plate 6 and its tail-piece 6', a cut-out 9 is provided to accommodate the hasp hinge barrel 3 and roll-like formations 9 are pro-- vided to encompass the attaching plate hinge barrels 4 and 5. The casing 9 is fastened to the attaching plate by means of securing tabs or lugs I0, which are clinched or bent around the ends of the attaching plate and under and around the tail-piece 6', as shown in Figures 2 to 6, inclusive. The hasp H is biased to swing to the position shown in dotted lines in Figure 3 by means of a spring designated generally at II, the spring II having coils I2 wrapped around one of the projecting ends of the hinge pin and havin the terminals I3 and I 4 projecting from the coils and engaging the attaching plate 6 and the body plate I of the hasp H, respectively.

A latching bolt designated generally at I5 is slidably fitted in the flanged body plate I of the hasp H. This latching bolt is also constituted of a sheet metal stamping and in general conforms in outline to the outline of the body plate I of the hasp, although, of course, it is appropriately smaller so that it may be slidably interfitted therewith, as illustrated to advantage in Figures 4 and 5.

The side edges of the latching bolt I5 have a free Sliding engagement with the opposed inner surfaces of the marginal flanges 2 of the body plate I of the hasp. For maintaining the latching bolt I5 assembled with the body plate I of the hasp H, and in proper sliding engagement therewith, a pair of lugs I6 are integrally formed with the opposed portions of the marginal flange 2 of the body plate I of the hasp H, and these lugs I6 are bent over the latching bolt I 5 and have their inner ends extended downwardly and in wiping contact with the underlying portions of the latching bolt I5. This feature is believed to be one of substantial practical advantage in that these two lugs I6 serve as the primary means which maintains all of the parts of the hasp assembled. No riveting or-welding is necessary although in one instance it is convenient to resort to resetting or staking, as will hereinafter more fully appear.

The latching'bolt I5 is biased'to latching position by a latch spring IT. This spring comprises a piece of appropriately shaped or bent and stifily resilient spring wire. An end I8 of the spring I1 is anchored or fixed to the latching bolt, as indicated at I 9. The spring I! beyond its point of attachment to the latching bolt is bowed or curved as at 20 and terminates in a leg 2I extending lengthwise of the hasp but tensioned and consequently transversely flexed or bowed. The end of the leg 2I bears against a suitable, fixed structure of the body plate of the hasp H and in the construction shown bears against the juncture of the body plate with the extension thereof that is formed into the hinge barrel 3.

\ A key-operated lock is combined with the latching bolt I5, and to adapt it for this purpose the enlarged portion of the latching bolt I5 has an opening 25 therein. The Opening 25 is illustrated as being of U shape. -However, its shape may be varied. Itis essential only that its upper and loweredges present stops or limiting edges for the tumbler26. A tumbler 26 is provided and is constituted of a cup-like sheet metal stamping (see Figures 14 and 15). The body 26' of the cup-shaped tumbler 26 is rotatably fitted on an inwardly directed boss 21 pressed from the body plate I of the hasp H (see Figures 2, 3, and '7). This boss 21 serves as a bearing for the tumbler 26. It also has a key-hole slot 28. The inward depression or recess which the boss 21 presents on the surface of the hasp serves as an escutcheon for indicating and facilitating the location 'of the key-receiving slot 28. The tumbler 26 has its inner end wall formedwith an integral inwardly displaced segmental projection 29 approximately in the form of a half circle in its outline and interfitted with the U-shapediopening 25 of the latching bolt. In the assembly the bowed or curved portion 20 of the latch spring I! extends around and engages the periphery of this segmental projection 29 so as to hold the tumbler in rotative engagement with its bearing 21 and to act as a frictional shoe or brake thereon'whereby to releasably secure the tumbler 26 in any position to which it is adjusted by its key. At one point of its periphery the circular body of the main, cup-like portion of the tumbler 26 has a stop lug struck outwardly therefrom. This lug 30 is in cooperative relation to stop lugsS-l and 32 struck up from the body of the latching bolt 15.

A key 33 is provided and has its shank 34 of such configuration and is so slotted as to correspond to the configuration of the ward-like formation of the keyhole slot 28 so that the key may be inserted in the keyhole slot and rotated after it has been completely inserted. The inner end of the key is provided with a short, circular stud 35 which extends into a'bearing opening 36 provided in the segmental projection 29 of the tumbler whereby the key is centered and supported for rotation. Adjacent the stud-like projection the key has two crank lugs 31 and 38 adapted to have driving engagement with the flat inner surfaces 39 and 40 of the segmental projection of the tumbler so that the key may be utilized to rotate the tumbler in either direction.

When the key rotates the tumbler in one direction, as, for example, from the position shown in Figure 4 to the position shown in Figure 6, the circular periphery of the projection 29 wipes past the curved portion of the opening 25 and into engagement with the transverse, flat, upper edge of the opening, thereby locking the latching bolt 15 against retraction to unlatched position. Reverse rotation of the key brings the tumbler back to the position shown in Figure 4, in which position the latching bolt I5 is released and may be unlatched upon further rotation of the key, or may be manually disengaged or unlatched.

For the purpose of manually shifting the latching bolt 15 from its latched to its unlatched position, a finger button 40' is provided. The head of the button is disposed on the outside of the body plate I of the hasp H, and its shank 4| extends through an elongated slot 42 provided in the plate I and the inner end of the button is staked or riveted or otherwise suitably secured to the latching bolt l5, as indicated at 43. The button 40 may be readily grasped and when the lock is unlocked may be utilized to press the latch to its unlatched position, Incidentally this button 40 also supplements the guiding action of the flanges 2 of the hasp body and of its guiding lugs The present invention may be utilized with either a surface or recess type of keeper. In the form of the invention shown in Figures 1 to 3,

the surface type of keeper is disclosed. This keeper comprises a box-like housing 45 stamped or drawn from sheet metal and having integrally attached prongs 46 which are driven through the part P and are staked over as at 41 to rigidly secure the keeper in place. The top wall of the keeper housing is incised and pressed inwardly to provide a floor 48, a keeper shoulder 49, and a locking shoulder 50, Therecess type of keeper, designated at K, and illustrated in Figure 18, is identical with the structure described, save that the marginal flange thereof is omitted, and that the part P is provided with a recess 52 to receive the keeper K.

of its latching or locking action. When desired the lock may be manipulated to secure the latching bolt in latching position, in the manner previously described.
